HOSE-COUPLING.

Specification of Letters Patent.

Patented Sept. 30, 1913.

Application filed September 23,1912. Serial No. 721,948.

7 following is a specification.

Our present invention relates to that class of couplings particularlyadapted for coupling a hose to the line pipes of air brakes and steamheating systems of railway cars, and is an improvement over the hosecoupling disclosed by our copending application, filed Oct. 7, 1912,Serial No. 653,409.,

Our objects are to provide a coupling which will retain air, steam,iorother fluid under pressure withoutleaking,one which can be readilycoupled without requiring the operator to pass between cars, and onewhich will automatically uncouple when the cars are uncoupled and drawnapart from each other. 7

Our coupling may also be used to advantage for coupling fire-hose towater plugs, and other purposes, and in order that the invention may befully understood, reference will now be made to the accompanyingdrawings, in which:

Figure 1 is a side elevation of the invention in operative position.Fig. 2 is a side elevation of one of the coupling members in position toreceivethe companion coupling member. Fig. 3 is a side elevation of thecoupling members connectedto each other. Fig. 4 is a front elevation ofthe coupling members connected. Fig. 5 is a longitudinal section on lineV-V of Fig. 3. Fig. 6 is a broken longitudinal section of a modifiedform of the invention. 1-1 designate two short pieces of pipe,communicating with two line pipes 22 through the intermediary ofangle-valves 33. The line pipes 22 extend beneath two railway cars (notshown) for the purpose of conducting air to the air-brakes or steam tothe heating system, installed on the cars. Each pipe 1, is provided atits lower threaded end with a coupling member 4, having a conical socket5, lined with Babbitt or other comparatively soft metal 6, having aninternal annular shoulder 7.

8 designatesa cam locking member, comprising a lever 9, a weight 10 atone end of said lever, and a pair of disks 11, integral with the ends ofthe bifurcated portion of lever 9. The outer facesof disks 11, haveeccentric recesses 12, for a purpose which will hereinafter appear.Disks 11, are journaled in annular flanges 13, projecting from oppositesides of the coupling member 4, and having integral guides 14 atopposite sides of openings 15 in said flanges.

16 designates a companion coupling member, having an integral nozzle 17,adapted to enter the conical socket 5 in the coupling member 4, and beseated in the annular shoulder 7, as shown of Fig. 5. Coupling member 16is provided with a pair of oppositely-disposed jaws 18, theupper freeends of which have inwardly-extending lugs 19, preferably elliptical incross section, so that they may readily pass through openings 15, whencoupling or uncoupling the members 4 and 16. i

20 20 designate nipples, screwed into the lower ends of coupling members16 to receive the end of a hose 21, secured thereto by clamps 22.

2323 designate clamps, secured to pipes 1 for the purpose of holding thecam-locking members 8 in the raised position, shown on Fig. 2.

p 24 designates a cable attached at one end to an eye 25 on weight 10,and extending through an eye 26, on the adjacent anglevalve 3. The upperend of cable 24, is provided with a ring 27, adapted to receive aresilient clasp 28, attached to one end of a cable 29, the opposite endof which is secured to an eye 30, with which each car-transom 31 isprovided.

32 designates a chain, depending from an eye 33 and provided at itslower end with a hook 34, whereby the free end of hose 21 may besupported, when the hose has been uncoupled at its end most remote fromeye 33.

In practice one end of the hose is, preferably, permanently coupled toone of the short pipes 1, so that when two cars come together, the freeend of the hose may be grasped with both hands to effect the coupling ofsaid free end to the short pipe 1, on the other car. The cable 29 isattached to the car on which the hose is to be left, so that when thecars are uncoupled and drawn apart from each other the hose isautomatically uncoupled from the other car by said cable 29, pullingupward on the cam looking member 8, until said cam locking member isgrasped by the adjacent clamp 23.

hen this occurs, the mouths of the recesses 12 are in coincidence withopenings 15, as shown on Fig. 2, and allow the lugs 19 on the opposingcoupling member to drop down through said openings and thus effect theuncoupling of members 4: and 16. After the cam locking member 8 has beendrawn upward into engagement with its respective clamp 23, the pull ofcable E29 causes clasp 28 to release ring 2'? and thus prevent breakingeither cable 2st or 29.

In coupling the members l and 16, nozzle 17 is firmly drawn against theannular shoulder 7, by the eccentric shoulders 35 on disks l1, engagingthe under sides of lugs 19, and said coupling members are reliably heldin coupled position by the downward pressure of lever 9 and weight 10 onsaid shoulders 35.

In the modified form disclosed by Fig. 6,

the construction of the coupling members is identical to that of thepreferred term, ex-

7 cept that nozzle l7 has an annular shoulder ried by the other member,an inwardly extending lug formed on each aw for engagement through saidrespective openings ot respective openings of the flanges to admit thelugs of the second named member 'on the interiors 0t sa1d eccentricrecesses, sald lugs being engaged by the walls formed by i the eccentricrecesses and being actuated thereby when the lever is operated.

2. A hose coupling embodying two interengaging members, a flange on eachside of one of said members formed with an opening which extends throughthe'fiange periphery, a pair of jaws carried by the other member forengagement through the respec- V tive openings of the'flanges, a diskrotatably supported by each flange, and a lever having one end securedto the disks, each disk having an eccentric recess the mouths of whichextend through the disk peripheries and are for registry with therespective openings of the flanges to admit the jaws of the second namedmember on the interiors of said eccentric recesses, said lugs beingengaged by the walls formed by the eccentric recesses and being actuatedthereby when the lever is operated.

in testimony whereof we aflix our signatures, in the presence of twowitnesses THOMAS CARENCE. ERNEST SUMPTER.
